Multitasking - is it possible?

I just read an article by Marilee Sprenger that was published in Sept. 2009 in Focusing the Digital Brain. In this article Ms. Sprenger discusses learning and teaching in the digital age. One of the items she focuses on is "multitasking." Her contention is that multitasking is virtually impossible. For the purposes of our discussion, let's say that multitasking is the ability to devote full attention to two or more tasks at the same time. I have enclosed a link to Ms. Sprenger's article.
